750 ILCS 5/505
(a) In a proceeding for dissolution of marriage, legal separation, declaration of invalidity of marriage, or dissolution of a civil union, a proceeding for child support following a legal separation or dissolution of the marriage or civil union by a court that lacked personal jurisdiction over the absent spouse, a proceeding for modification of a previous order for child support under Section 510 of this Act, or any proceeding authorized under Section 501 or 601 of this Act, the court may order either or both parents owing a duty of support to a child of the marriage or civil union to pay an amount reasonable and necessary for support. The duty of support owed to a child includes the obligation to provide for the reasonable and necessary physical, mental and emotional health needs of the child. For purposes of this Section, the term "child" shall include any child under age 18 and any child over the age of 18 who has not attained age 19 and is still attending high school. For purposes of this Section, the term "obligor" means the parent obligated to pay support to the other parent.
(1) Child support guidelines. The Illinois Department of Healthcare and Family Services shall adopt rules establishing child support guidelines which include worksheets to aid in the calculation of the child support obligations and a schedule of basic child support obligations that reflects the percentage of combined net income that parents living in the same household in this State ordinarily spend on their child. The child support guidelines have the following purposes:
(1.5) Computation of basic child support obligation. The court shall compute the basic child support obligation by taking the following steps:
(D) calculate each parent's percentage share of the basic child support obligation.
Although a monetary obligation is computed for each parent as child support, the receiving parent's share is not payable to the other parent and is presumed to be spent directly on the child. (2) Duty of support. The court shall determine child support in each case by applying the child support guidelines unless the court makes a finding that application of the guidelines would be inappropriate, after considering the best interests of the child and evidence which shows relevant factors including, but not limited to, one or more of the following: (A) the financial resources and needs of the child;
(3) Income.
(C) As used in this Section, "standardized tax amount" means the total of federal and state income taxes for a single person claiming the standard tax deduction, one personal exemption, and the applicable number of dependency exemptions for the minor child or children of the parties, and Social Security and Medicare tax calculated at the Federal Insurance Contributions Act rate.
(D) As used in this Section, "individualized tax amount" means the aggregate of the following taxes:
(F) Adjustments to income.
(3.1) Business income. For purposes of calculating child support, net business income from the operation of a business means gross receipts minus ordinary and necessary expenses required to carry on the trade or business. As used in this paragraph, "business" includes, but is not limited to, sole proprietorships, closely held corporations, partnerships, other flow-through business entities, and self-employment. The court shall apply the following:
(11) record of seeking work.
The court shall also consider the local job market, availability of local employers willing to hire the parent, prevailing earning levels in the local community, and other relevant background factors in the case. If there is insufficient work history to determine employment potential and probable earnings level, there shall be a rebuttable presumption that the parent's potential income is 75% of the most recent United States Department of Health and Human Services Federal Poverty Guidelines for a family of one person. Incarceration shall not be considered voluntary unemployment for child support purposes in establishing or modifying child support. (3.2b) The court may impute income to a party only upon conducting an evidentiary hearing or by agreement of the parties. Imputation of income shall be accompanied by specific written findings identifying the basis or bases for imputation using these factors. (3.3) Rebuttable presumption in favor of guidelines. There is a rebuttable presumption in any judicial or administrative proceeding for child support that the amount of the child support obligation that would result from the application of the child support guidelines is the correct amount of child support. (3.3a) Minimum child support obligation. There is a rebuttable presumption that a minimum child support obligation of $40 per month, per child, will be entered for an obligor who has actual or imputed gross income at or less than 75% of the most recent United States Department of Health and Human Services Federal Poverty Guidelines for a family of one person, with a maximum total child support obligation for that obligor of $120 per month to be divided equally among all of the obligor's children. (3.3b) Zero dollar child support order. For parents with no gross income, who receive only means-tested assistance, or who cannot work due to a medically proven disability, incarceration, or institutionalization, there is a rebuttable presumption that the $40 per month minimum support order is inapplicable and a zero dollar order shall be entered. (3.4) Deviation factors. In any action to establish or modify child support, whether pursuant to a temporary or final administrative or court order, the child support guidelines shall be used as a rebuttable presumption for the establishment or modification of the amount of child support. The court may deviate from the child support guidelines if the application would be inequitable, unjust, or inappropriate. Any deviation from the guidelines shall be accompanied by written findings by the court specifying the reasons for the deviation and the presumed amount under the child support guidelines without a deviation. These reasons may include: (A) extraordinary medical expenditures necessary to preserve the life or health of a party or a child of either or both of the parties; (B) additional expenses incurred for a child subject to the child support order who has special medical, physical, or developmental needs; and (C) any other factor the court determines should be applied upon a finding that the application of the child support guidelines would be inappropriate, after considering the best interest of the child. (3.5) Income in excess of the schedule of basic child support obligation. A court may use its discretion to determine child support if the combined adjusted net income of the parties exceeds the highest level of the schedule of basic child support obligation, except that the basic child support obligation shall not be less than the highest level of combined net income set forth in the schedule of basic child support obligation. (3.6) Extracurricular activities and school expenses. The court, in its discretion, in addition to the basic child support obligation, may order either or both parents owing a duty of support to the child to contribute to the reasonable school and extracurricular activity expenses incurred which are intended to enhance the educational, athletic, social, or cultural development of the child. (3.7) Child care expenses. The court, in its discretion, in addition to the basic child support obligation, may order either or both parents owing a duty of support to the child to contribute to the reasonable child care expenses of the child. The child care expenses shall be made payable directly to a party or directly to the child care provider at the time of child care services. (A) "Child care expenses" means actual expenses reasonably necessary to enable a parent or non-parent custodian to be employed, to attend educational or vocational training programs to improve employment opportunities, or to search for employment. "Child care expenses" also includes deposits for securing placement in a child care program, the cost of before and after school care, and camps when school is not in session. A child's special needs shall be a consideration in determining reasonable child care expenses. (B) Child care expenses shall be prorated in proportion to each parent's percentage share of combined net income, and may be added to the basic child support obligation if not paid directly by each parent to the provider of child care services. The obligor's and obligee's portion of actual child care expenses shall appear in the support order. If allowed, the value of the federal income tax credit for child care shall be subtracted from the actual cost to determine the net child care costs. (C) The amount of child care expenses shall be adequate to obtain reasonable and necessary child care. The actual child care expenses shall be used to calculate the child care expenses, if available. When actual child care expenses vary, the actual child care expenses may be averaged over the most recent 12-month period. When a parent is temporarily unemployed or temporarily not attending educational or vocational training programs, future child care expenses shall be based upon prospective expenses to be incurred upon return to employment or educational or vocational training programs. (D) An order for child care expenses may be modified upon a showing of a substantial change in circumstances. The party incurring child care expenses shall notify the other party within 14 days of any change in the amount of child care expenses that would affect the annualized child care amount as determined in the support order. (3.8) Shared physical care. If each parent exercises 146 or more overnights per year with the child, the basic child support obligation is multiplied by 1.5 to calculate the shared care child support obligation. The court shall determine each parent's share of the shared care child support obligation based on the parent's percentage share of combined net income. The child support obligation is then computed for each parent by multiplying that parent's portion of the shared care support obligation by the percentage of time the child spends with the other parent. The respective child support obligations are then offset, with the parent owing more child support paying the difference between the child support amounts. The Illinois Department of Healthcare and Family Services shall promulgate a worksheet to calculate child support in cases in which the parents have shared physical care and use the standardized tax amount to determine net income. (3.9) Split physical care. When there is more than one child and each parent has physical care of at least one but not all of the children, the support is calculated by using 2 child support worksheets to determine the support each parent owes the other. The support shall be calculated as follows: (A) compute the support the first parent would owe to other parent as if the child in his or her care was the only child of the parties; then (B) compute the support the other parent would owe to the first parent as if the child in his or her care were the only child of the parties; then (C) subtract the lesser support obligation from the greater.
The parent who owes the greater obligation shall be ordered to pay the difference in support to the other parent, unless the court determines, pursuant to other provisions of this Section, that it should deviate from the guidelines. (4) Health care to be addressed by the court.
(C) If neither parent has access to appropriate private health insurance coverage, the court may order:
(a-3) Life insurance to secure support. At the discretion of the court, a child support obligation pursuant to this Section and Sections 510, 513, and 513.5 of this Act may be secured, in whole or in part, by reasonably affordable life insurance on the life of one or both parents on such terms as the parties agree or as the court orders. The court may require such insurance remain in full force and effect until the termination of all obligations of support, subject to the following:
(b) Failure of either parent to comply with an order to pay support shall be punishable as in other cases of contempt. In addition to other penalties provided by law the court may, after finding the parent guilty of contempt, order that the parent be:
(2) sentenced to periodic imprisonment for a period not to exceed 6 months; provided, however, that the court may permit the parent to be released for periods of time during the day or night to:
(B) conduct a business or other self-employed occupation.
The court may further order any part or all of the earnings of a parent during a sentence of periodic imprisonment paid to the Clerk of the Circuit Court or to the parent having physical possession of the child or to the non-parent custodian having custody of the child of the sentenced parent for the support of the child until further order of the court.
If a parent who is found guilty of contempt for failure to comply with an order to pay support is a person who conducts a business or who is self-employed, the court in addition to other penalties provided by law may order that the parent do one or more of the following: (i) provide to the court monthly financial statements showing income and expenses from the business or the self-employment; (ii) seek employment and report periodically to the court with a diary, listing, or other memorandum of his or her employment search efforts; or (iii) report to the Department of Employment Security for job search services to find employment that will be subject to withholding for child support.
If there is a unity of interest and ownership sufficient to render no financial separation between an obligor and another person or persons or business entity, the court may pierce the ownership veil of the person, persons, or business entity to discover assets of the obligor held in the name of that person, those persons, or that business entity. The following circumstances are sufficient to authorize a court to order discovery of the assets of a person, persons, or business entity and to compel the application of any discovered assets toward payment on the judgment for support:
(3) the obligor transfers assets to the person, persons, or business entity with the intent to perpetrate a fraud on the obligee. With respect to assets which are real property, no order entered under this paragraph shall affect the rights of bona fide purchasers, mortgagees, judgment creditors, or other lien holders who acquire their interests in the property prior to the time a notice of lis pendens pursuant to the Code of Civil Procedure or a copy of the order is placed of record in the office of the recorder of deeds for the county in which the real property is located.
The court may also order in cases where the parent is 90 days or more delinquent in payment of support or has been adjudicated in arrears in an amount equal to 90 days obligation or more, that the parent's Illinois driving privileges be suspended until the court determines that the parent is in compliance with the order of support. The court may also order that the parent be issued a family financial responsibility driving permit that would allow limited driving privileges for employment and medical purposes in accordance with Section 7-702.1 of the Illinois Vehicle Code. The Clerk of the Circuit Court shall certify the order suspending the driving privileges of the parent or granting the issuance of a family financial responsibility driving permit to the Secretary of State on forms prescribed by the Secretary of State. Upon receipt of the authenticated documents, the Secretary of State shall suspend the parent's driving privileges until further order of the court and shall, if ordered by the court, subject to the provisions of Section 7-702.1 of the Illinois Vehicle Code, issue a family financial responsibility driving permit to the parent.
In addition to the penalties or punishment that may be imposed under this Section, any person whose conduct constitutes a violation of Section 15 of the Non-Support Punishment Act may be prosecuted under that Act, and a person convicted under that Act may be sentenced in accordance with that Act. The sentence may include but need not be limited to a requirement that the person perform community service under Section 50 of that Act or participate in a work alternative program under Section 50 of that Act. A person may not be required to participate in a work alternative program under Section 50 of that Act if the person is currently participating in a work program pursuant to Section 505.1 of this Act.
A support obligation, or any portion of a support obligation, which becomes due and remains unpaid as of the end of each month, excluding the child support that was due for that month to the extent that it was not paid in that month, shall accrue simple interest as set forth in Section 12-109 of the Code of Civil Procedure. An order for support entered or modified on or after January 1, 2006 shall contain a statement that a support obligation required under the order, or any portion of a support obligation required under the order, that becomes due and remains unpaid as of the end of each month, excluding the child support that was due for that month to the extent that it was not paid in that month, shall accrue simple interest as set forth in Section 12-109 of the Code of Civil Procedure. Failure to include the statement in the order for support does not affect the validity of the order or the accrual of interest as provided in this Section.
